Sega Sports' World Series Baseball, or simply World Series Baseball, is a sports game developed by BlueSky Software and published by Sega for the Genesis/Mega Drive and Game Gear.

San Diego Padres broadcaster Jerry Coleman provides the play-by-play for the game.

The first World Series Baseball officially licensed by the MLB was released by Mattel Electronics for the Intellivision in 1983 with a stunning 3D graphic.

GamePro gave the Genesis version a rave review, calling it "arguably the best baseball cart ever."

They praised the use of real life teams, players, and stadiums, the accurate graphical recreation of the stadiums, the catcher's-eye view of the action, and the generally impressive graphics.
